Value Collection 454544PR Hex Head Cap Screw 3/4-16 X 1-1/2 in Grade 8

Product Description

The VALUE COLLECTION 454544PR is a fully threaded hex head cap screw designed for high-strength fastening applications in industrial, mechanical, and structural assemblies. It features a 3/4-16 UNF thread size and measures 1.5 inches under the head. Manufactured from Grade 8 steel, this fastener delivers high tensile strength and fatigue resistance. The zinc yellow dichromate finish provides corrosion protection and is easily identifiable by its distinctive yellow coating. Meets ASME B18.2.1 standards, making it suitable for precision and code-referenced installations. Installed using a 1-1/8 inch hex key or wrench drive.

This cap screw is appropriate for medium-to-heavy mechanical assemblies where a fine-thread, high-strength fastener is required. Fine-thread UNF fasteners like this one are commonly used in applications requiring greater thread engagement, vibration resistance, or precise torque control. Typical uses include equipment mounting, machinery repair, automotive, and structural fabrication work. The fully threaded shank maximizes thread engagement along the entire grip length, making it well suited for thinner material applications and adjustable joint assemblies.

Key Features

• Grade 8 steel construction provides high tensile and proof load strength
• Fully threaded shank for maximum thread engagement
• 3/4-16 UNF fine-thread profile for vibration-resistant fastening
• Zinc yellow dichromate finish offers corrosion protection and visual identification
• Conforms to ASME B18.2.1 dimensional standards
• 1-1/8 inch hex drive for standard socket or wrench installation

Compatibility

Designed as a standard replacement or stock fastener for assemblies requiring a 3/4-16 UNF fully threaded hex head cap screw in Grade 8 steel with a zinc yellow dichromate finish, conforming to ASME B18.2.1.

Installation Notes

Installation is performed using a 1-1/8 inch socket or combination wrench. De-energize and lock out all relevant equipment before fastener installation or replacement in any mechanical or electrical assembly. Follow applicable torque specifications from the equipment manufacturer or relevant ASME or industry fastener standards for the joint material and grade. Inspect threads and mating surfaces for damage before installation to ensure a proper fit and full load-bearing capacity.
